我正在尝试使用此代码( https://www.w3schools.com/howto/howto_css_modal_images.asp)在单击包含文本(而不是图像)的 div 后显示并对其进行缩放,但这不起作用。

当我单击包含文本的 div 时,我希望获得相同的效果,但我认为此代码仅对图像有效?

我试过这个:

HTML:

<!DOCTYPE>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<title></title>
</head>
<body>
<!-- Trigger the Modal -->
<div id="myImg">
<p>Hello world</p>
</div>

<!-- The Modal -->
<div id="myModal" class="modal">

<!-- The Close Button -->
<span class="close">&times;</span>

<!-- Modal Content (The Image) -->
<img class="modal-content" id="img01">

<!-- Modal Caption (Image Text) -->
<div id="caption"></div>
</div>

<script type="text/javascript" src="script.js"></script>
</body>
</html>

CSS

/* Style the Image Used to Trigger the Modal */
#myImg {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}

#myImg:hover {opacity: 0.7;}

/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.9); /* Black w/ opacity */
}

/* Modal Content (Image) */
.modal-content {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
}

/* Caption of Modal Image (Image Text) - Same Width as the Image */
#caption {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
text-align: center;
color: #ccc;
padding: 10px 0;
height: 150px;
}

/* Add Animation - Zoom in the Modal */
.modal-content, #caption {
animation-name: zoom;
animation-duration: 0.6s;
}

@keyframes zoom {
from {transform:scale(0)}
to {transform:scale(1)}
}

/* The Close Button */
.close {
position: absolute;
top: 15px;
right: 35px;
color: #f1f1f1;
font-size: 40px;
font-weight: bold;
transition: 0.3s;
}

.close:hover,
.close:focus {
color: #bbb;
text-decoration: none;
cursor: pointer;
}

/* 100% Image Width on Smaller Screens */
@media only screen and (max-width: 700px){
.modal-content {
width: 100%;
}
}

JAVASCRIPT

// Get the modal
var modal = document.getElementById("myModal");

// Get the image and insert it inside the modal - use its "alt" text as a caption
var div = document.getElementById("myImg");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
div.onclick = function(){
modal.style.display = "table-row";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}



最佳答案

我强烈建议您花时间复习 CSS(和 JavaScript),特别是了解您现在可以使用 CSS 完成的所有操作。

.zoom:active {transform: scale(2, 2.5);}
